Answer:

First off, 3.4 / 342 = 0.01, not 0.001, so moles H = 0.22, not 0.022.

Then you multiplied the erroneous 0.022 x 6.022 x 10^22. Avogadro's number = 6.022 x 10^23, not 10^22! So your final answer should be 1.3 x 10^23 H atoms (choice B).

Your reasoning was right on, just a few math errors.
